ERNST KOERTING, OF PEGLI, NEAE, GENA, ITALY, ASSIGNURTO SCHUTTE EL KOEi/TING v- COMPANY, QF PHILADELPHIA, PENNSK'LVANIA, A CORPORATION 01?" PENNSYL- T o all whom z may concern:

Be it known that l, ERNST Kona'rING, a subject of 'the German Emperor, residing at Pegli, near Genoa, italy, have invented vcertain new and .useful'lmprovements in elet Apparatus, fully described and represented in the following specification and theac@ The object of the invention is to increase the etlieiency, and more especially the capacity-7 of a high pressure iet apparatus, that is, one in which the momentum of the `iet is sulilcient to force the gas against a considerable diderence in pressure between the suction side and the discharge side of the apparatus, Whether used as a suction yor a forcing or compressing pump or as a condenser. To this end I provide the apparatus with means to produce fissures in the jet into which the gas may enter to get to the core of the jet, means being preferably provided also for facilitating the entrance of the gas into such fissures. By

producing such gas-receiving fissures inthe actuating jet, the surface area of the liquid with which the gas comes into Contact is greatly increased, while the direction of flow of the jet is'not affected and the energy of the jet is not substantially diminished.

full understanding of the invention can est hegiven by detailed description of n apparatus yembodying the various features of he invention in an approved form, and such a description Will now be given in connection with the accompanying drawings, in which,

l? i ure 1 is a central sectional view of a simp e formv of apparatus made in accordance'with the invention. Fig. 2 is a section of the water iet nozzle taken on .line 2 of l. Fig. 3 is a similar View of a further modilioation. Fig. 4 is a section taken on line l of Fig, 3.' A

Referring to the drawings, and rst to Figs. l and the Water jet nozzle l0 ex tends into a supply chamber 11 in position to discharge water received from the waterl v supply pipe i2 in the form of a jet into the end of a combining tube which extends chamber 11.

The combining tubedischarges through a diverglng discharge tube or pressure cone 14. The air, steam or other gas enters the supply chamber 11 through an inlet l5. In order to form the gas-receiving fissures in the solid jet the nozzle 1.0 is provided at its discharge end or mouth with one or more jet openers 20 extending inward from the nozzle Wall, there being preferably a plurality of such openers arranged radially as shown 1n Figs. 2 and 3. These openers may extend clear in tothe axial line of the nozzle as shown in-Figs. l and 2 or the openers may end short of the axial line as shown in Figs. 3 and 4. The openers are best made of inwardly tapering form as shoivn so that the lissures in the jet will 'be of inwardly taper ing or Wedge shape, and the openers are best made of a depth or length in the direction of the movement yof the jet considerably greater than their thickness and with their upper or outer portions tapered olf to pro- (lll Vide sharp edges, thus insuring a straight v flow Without oscillation. As the opened jet issues from the nozzle and enters the combining tube, the gas from the chamber 1l will not only come in Contact with the outer surface of the jet and be drawn into the combining tube through such Contact, 'but will also enter the fissures in the jet, and the extent of surface of the jet with which To secure the greatest benefit from the increased area of contact between the .liquid and the gas due to the fissures in the jet the combining tube is formed with openings in its upper portion in line with the openers 20 through which as from the chamber 11 may pass to enter t e iissures in the jet after the jet has entered the mouth of the combining tube. These openings are shown as formed by longitudinal slits 21 extending from the upper end of the combining tube in alinement with the dividersQO.

The nozzle should be set close to the mouth of the combining tube as shown so that the split or lissured jet Will come into action in the combining' tube so faras possible without loss of the form in which it issues chamber or combining tube and Aits. cross A sectional area` at its narrowest point will vary according to the character of the gas to be moved. If the gas is such that condenation or absorption bythe liquidtakes place, the combining tube will be reduced as indicated by dotted lines in Fig. -1 more. or less according as the condensatiuh or absorption is perfect or only partial. The length of the combining tube, also, in such case will depend on the rapidity ofabsorption or condensation and also on the size and number of the fissures formed 4in thejet.

vThe openers 20 may be formed separately from the nozzle and set removably or perw manently in position in the mouth of the nozzle. W hen the openers end shortl of the axial line of the nozzle and are not joined together centrally they may be carried by a ring 22 as shownv in Figs. 3 and 4. Other arrangements of the openers for 'producing a iissured jet with comparatively deep and more or less narrowissures therein may be employed. f.

It'will be seen 'that-'the apparatus of the invention is a high pressure'apparatus,

that is, an apparatus in W'hichthe actuating jet has such volume andveloeity that its momentum or propelling energy'isnsuiiicient tb force the gas against a considerable diference in pressure betweenthe suction side and the discharge side of the apparatus.

What is claimed is: x

1. A high pressure liquid-jet apparatus, comprising in combination a combining tube and a pressure cone leading therefrom, and a nozzle formed to discharge a high-velocity impelling jet of liquid into the combining tube, said nozzle having iet openers to form gas-receiving fissures in the `iet opening inward from the outer surface of the jet and being a suliicient distance apart to avoid destroying the solidity of the intervening portions of the jet, and the combining tube and pressure cone being formed to permit unimpeded passage of the issured jet. 2. A high pressure liquid-jet apparatus, comprising in combination a combining tube and a pressure cone leading therefrom, and a nozzle formed to discharge a higl'i-velocity limpelling jet of liquid into the combining tube, said nozzle having getopeners to form gas-receiving fissures in the jet opening inward vfrom the outer surface of the and beinglxa suliicient distance apart to avoid destroying the solidity 'of the intervening portions ol the jet, and means `tor directing the gas into such fissures, the combining tubeand pressure conebeing formed to permit unimpeded passage of the iissured jet.
